ABSTRACT:
A beam scan type recording apparatus for scanning a laser beam periodically on a photosensitive medium for recording a visible image comprised of dot images is disclosed. In the recording apparatus, numerical data representing time interval between emission timings of the laser beam corresponding to respective dot images are stored in a memory. A dot clock counter outputs a dot clock signal when the counting value thereof agrees with a value preset from the memory, and a laser is driven so as to emit the laser beam according to image data in synchronous with the dot clock signal.
